Ventilated façades can help to reduce summer building thermal loads and, therefore, energy consumption due air-conditioning systems thanks the combined effect of solar radiation reflection and natural or forced ventilation into cavity. The evaluation ventilated behavior performance is complex requires a complete thermo-fluid dynamic analysis. In this study, computational fluid (CFD) methodology...

Ventilated façades have become an increasingly employed feature in the design of low energy buildings over recent years in that they offer the attractive features of a conventional glass façade but without the thermal disadvantages. These façades consist of a double skin surface, the outer layer of which is of toughened glass, and the inner layer of which usually comprises conventional double-g...

Reducing vessel resistance by using ventilated cavities has been a highly researched topic in the marine industry. There is limited literature on supercavities near free surface, which indicates that their dynamic behavior more complex than conventional due to effect of surface. This paper employs numerical simulations study supercavity, taking into account Numerical can predict gas leakage beh...

In this paper, a novel analytical method was developed based on statistical energy analysis framework to evaluate sound transmission loss through ventilated windows. The proposed method was compared to numerical and analytical models available in the literature. Results showed the success and advantage of the proposed model in predicting the acoustic performance of the ventilated window and the...

The objective of this paper is to investigate the effect two typical supercavity flow patterns (double-cavity and wake-closure) on ventilated geometry supercavitating structure further reveal different mechanisms gas leakage for these patterns. An inhomogeneous multiphase model with shear stress transport turbulence was employed validate investigation by experimental results. investigated quant...
